This Pololu caster uses a 1/2" plastic ball to give a nice, low-friction ride at a height of 0.53" to 0.72"


Additional Information [Hide]

It seems the lucky goons at Pololu have had a series of low-friction casters made from a 3D printer. This means it's got some pretty nice design points, and with a 1/2" plastic ball, it offers a nice, low-friction ride at a height of 0.53" to 0.72"

The kit features black ABS housing, a 1/2" diameter ball, and two spacers (1/16" & 1/8" thick), and a pair of #2 nut/bolt sets.

And weighing only 2 grams, it's light!
